SkySafari is a powerful planetarium that fits in your pocket, puts the universe at your fingertips, and is incredibly easy to use!

Simply hold your device to the sky and quickly locate planets, constellations, satellites, and millions of stars and deep sky objects. Use Augmented Reality (AR) mode to blend a simulated sky chart with a real view of your surroundings.

Packed with interactive information and rich graphics, discover why SkySafari 6 is your perfect stargazing companion under the night sky.

Here's what's new in version 6:

1) Complete support for iOS 11 and iPhone X. We got you covered and release regular updates.

2) Clouds and Astronomy. Two words that rarely go together. Rewritten from the ground up, SkySafari 6 will (optionally) back up all your settings files and make it easily accessible to multiple devices as well as from our new web interface,

3) Say It. Ever just wanted to just yell at your device and tell it what to do!? SkySafari 6 adds basic voice control for a wide range of operations. Say “select Jupiter,” “search for Titan,” “center on Polaris” and SkySafari will do the work for you. Yelling optional. 

4) Redesigned toolbar with ability to hide

5) Configurable font sizes

6) Better control of magnitude limits

7) Improved databases

8) Better updating of Comets and Asteroids  (more recent data)

What's New

Version 6.2.1

Minor Update:

+ Improved accuracy of planetary position predictions.
+ Improved memory usage.
+ Improvements to syncing data with LiveSky server.
+ Fixed bug where the AR button was shown on top of the "Current List" button when it was visible.
+ Fixed bug where you could get stuck in Stereographic projection after using AR mode.

What's New in 6.2.0

SkySafari can now show you an Augmented Reality (AR) view of the sky! AR blends a simulated sky chart of your sky with a real view of your surroundings, captured from your device's camera. AR mode makes it even easier to find your favorite planets, stars, and constellations.
+ iOS 10

Some pointers on using AR mode in SkySafari:

To use AR in SkySafari, first activate the compass by either tapping the icon in the toolbar or simply tilting your device up to the sky. A small AR icon appears above the toolbar, near the bottom of the screen. Tap the AR icon to turn on your device's camera. If this is the first time you've used AR, your device will ask for your permission to use the camera. To turn off AR mode, tap the AR icon again. When AR is active, the toolbar and on-screen buttons will be hidden.

During daylight hours, point your device's camera at an area of clear blue sky. SkySafari will fill that area with a star chart. At night, point your camera at a black sky area. SkySafari will attempt to draw the star chart only over the sky area, and not walls, buildings, trees, etc.

You can increase or decrease the amount of sky chart blending with the camera's video image by swiping up or down. At maximum blending, the star chart is drawn everywhere above the horizon, not just in clear sky areas.

You may find that the simulated objects in the sky chart don't quite line up correctly with the real objects shown by the camera. This is due to the inaccuracy inherent in your device's digital compass. To fix this problem, swipe the chart left-to-right. This way, you can align objects drawn in the chart with their images shown by the camera. The Moon is a great object to align on. The planets and brightest stars should also be visible in the camera and can be used for AR alignment.

A little disappointing

My initial reaction was a little disappointed. The app returns to wherever I last looked. There doesn’t seem to be an easy way to get back to the sky overhead at today’s date and time. Would be nice to have something to center on the current zenith. Also when I used the search feature the app did not have many of the objects I would have expected to be included. Many of the popular nebulae are missing. For example the horse head nebula. I tried searching for the common name and the official designation. The add-in purchase of cosmos does not appear to add those objects. If it did, I would probably purchase the add-in. Overall, I was disappointed. I have several other astronomy apps installed and this one is slightly different but at first experience, does not seem to be any better than the others. I do not own a telescope that supports “control”, so sky safari pro is not an appropriate purchase.

Hi, you can press the Time icon in the Toolbar and then press "Now" to set the date and time to the current date. Some users do prefer the app to start where they left off, but we'll revisit this and might include a preference or change the default behavior. SkySafari AR does include hundreds of deep sky objects but only SkySafari Plus and Pro include extended databases with fainter objects. We'll consider your request, perhaps the NGC-IC database can be included in the Cosmos Collection. Thank you again for taking the time to write a constructive review. Really appreciate it!

Couldn’t be better!

This app is amazing! I’ve been using Star Chart for the longest time, drooling to get my hands on this. Now it’s free! However, it might be a little difficult for first time stargazers because it can have a lot of distractions. I love the voice control, it really helps free up my hands. Forty dollars is a lot for an app, but I love this so much, I think Pro will definitely be worth it. I was surprised to find that it has little to no lag even with all of the items to display. It is a high quality app and I thank Simulation Curriculum.

Thank you so much for your comments. Enjoy the app!

I can spend hours . . .

What a app for astronomy buffs! Locate (within a reasonable proximity) that dot of light you see, find out what is known about it, follow its path, past or future, and get updates on upcoming astronomical events! I used it to observe the recent blue (accurately, Orange) super moon eclipse at totality just before dawn, knowing that since it calculates the viewing perspective from my exact location, I could get the eclipse right in the stage I wanted and know exactly where in the sky it was going to be. I like the music, too, but it can be turned off and on.

Developer Response

Thank you! The ambient sound can be turned off or you can select a different track - it's a fun feature for most but optional.
